Amazon Web Services isn’t just the biggest cloud provider. It’s also sitting on the largest pile of data center capacity in the world. AWS currently operates roughly 2.3 gigawatts of active IT capacity. Meta trails at 1.5 GW, Microsoft Azure sits at 1.2 GW, and Google Cloud rounds out the top four at 508 megawatts.

The spending spree that’s rewriting corporate budgets

The three biggest hyperscalers, Amazon, Microsoft, and Alphabet, now account for more than 60% of global hyperscale data center capacity. Combined capital expenditures from these companies are projected to exceed $350 billion in 2025. By 2026, that number could push toward $400 billion.

Amazon has been investing heavily in AI-specific infrastructure, including its ambitious Project Rainier supercluster. Google’s cloud division is adding capacity at the fastest rate among the group, with a particular emphasis on doing it cleanly.
